Description

一种双灯板照明台灯
技术领域
本实用新型涉及LED照明领域，更具体的，涉及一种供读写作业用的双灯板照明台灯。
背景技术
现有技术的大多数LED照明台灯只能用作普通照明或辅助照明，而不能作为读写作业照明用，即照度、均匀度和遮光性等光度学性能不能满足国家标准《读写作业台灯性能要求》（GB/T 9473-2008）的相关要求。
有的LED台灯虽然局部照度能达到读写作业照明的要求，但照射范围小，或照射区域利用率不高，照度均匀度不佳，造成光源浪费。又或者有的LED台灯为了提高照射范围的利用率，设计为灯体可翻转的形式，通过翻转调节灯体的照射角度，使得照射区域能够随着读写作业位置的变动而变动，但通过翻转灯体来调节照射范围将使得使用者在正常工作位置看到光源或反射器内壁，造成遮光性不能达到国家标准，对人眼有一定的损害。
发明内容
鉴于现有技术的读写作业台灯有如上所述缺点，本实用新型提供一种双灯板照明台灯，其解决了现有的读写作业照明台灯照度、均与度、遮光性不佳等问题，能满足国家标准《读写作业台灯性能要求》（GB/T 9473-2008）相关要求，而且光源得到充分利用，使用方便。
